In this earthquake detection control device 11, information on various electric devices and gas devices as control target devices to be controlled at the time of disaster is registered in advance. Moreover, the seismic intensity of the earthquake used as the reference | standard which judges that it is abnormal is set to this earthquake detection control apparatus 11 as a control condition for every control object apparatus. At this time, the earthquake detection control device 11 turns off the power according to the occurrence of an earthquake having a seismic intensity of 4 or more for the television 13 as the control target device, and responds to the occurrence of an earthquake of seismic intensity of 3 or more for the gas stove 14. Thus, different control conditions can be arbitrarily set depending on the control target device, such as turning off the power. When such an earthquake detection control device 11 detects an earthquake having a seismic intensity equal to or higher than a reference value set as a control condition, various types of electrical equipment such as a television 13 and various gas equipment such as a gas stove 14 provided in the facility are used. A control signal is transmitted via the communication means, and control is performed so that the power supply is turned off. Moreover, if the earthquake detection control apparatus 11 detects the earthquake of the seismic intensity more than a reference value, it will transmit a control signal via a communication means with respect to the mobile telephone 15 which the user US possesses as needed, and an alarm sound And control to display the alarm screen and the like. Furthermore, when the earthquake detection control device 11 detects an earthquake having a seismic intensity equal to or higher than a reference value, the earthquake detection control device 11 receives a radio 16 that receives broadcasts of disaster information or the like and a battery-type emergency light 17 provided in the facility as necessary. Then, a control signal is transmitted through the communication means, and the power is controlled to be turned on.

  The fire detection control device 12 includes a communication unit that performs wireless communication based on Bluetooth on a normal fire detection device that detects the occurrence of a fire. In the fire detection control device 12, information on various electric devices and gas devices as control target devices to be controlled in a disaster is registered in advance. In addition, the fire detection control device 12 is set with a fire degree serving as a reference for determining that there is an abnormality as a control condition for each control target device. At this time, similarly to the earthquake detection control device 11, the fire detection control device 12 can arbitrarily set different control conditions depending on the control target device. When such a fire detection control device 12 detects a fire having a fire degree equal to or higher than a reference value set as a control condition, as in the case of the earthquake detection control device 11, various electric devices as control target devices provided in the facility A control signal is transmitted to the gas appliance, the mobile phone 15 possessed by the user US, the radio 16 and the emergency light 17 via the communication means, and the operation is controlled.

  It is desirable that the earthquake detection control device 11 and the fire detection control device 12 include a battery for supplying power. That is, it is considered that the earthquake detection control device 11 and the fire detection control device 12 normally operate based on the AC power supplied via the facility wall outlet, while no power is supplied in the event of an abnormality. And it is comprised so that it may operate by switching the battery etc. with which it is provided to a drive electric power source.

  As described above, the electrical equipment and gas equipment control system uses each electrical equipment and gas equipment as control target equipment as terminals constituting a wireless communication network based on Bluetooth, and these terminals are used for the earthquake detection control device 11 and the fire detection. The control is performed by the control device 12.

  In such an electric device and gas device control system, the electric device and the gas device are initially registered as control target devices in the earthquake detection control device 11 and the fire detection control device 12.

  Specifically, as shown in FIG. 2, when the earthquake detection control device 11 and the fire detection control device 12 shift to a setting mode for addresses and control conditions assigned to each electric device and gas device in step S1, In step S2, the address of these devices and the control conditions such as the seismic intensity and the fire level for turning on or off the device are set.

In the electric device and gas device control system, by performing such initial registration, the earthquake detection control device 11 and the fire detection control device 12 can recognize the electric device and the gas device as control target devices.

  Further, in the electrical equipment and gas equipment control system, when initial registration of the control target device is performed by the earthquake detection control device 11 and the fire detection control device 12, the earthquake detection is performed according to the power on or off of the control target device. Registration or deregistration under management by the control device 11 and the fire detection control device 12 is performed.

  Specifically, as shown in FIG. 3, when an electric device or a gas device performs a startup process in step S <b> 11 by turning on a power source, an address signal indicating an address assigned to itself in step S <b> 12. , And a power-on signal indicating that the power source is turned on are transmitted to the earthquake detection control device 11 and the fire detection control device 12.

  In response to this, the earthquake detection control device 11 and the fire detection control device 12 perform an interrupt process for recognizing a control target device that is turned on among registered control target devices and registering it under management. That is, in step S13, the earthquake detection control device 11 and the fire detection control device 12 receive the address signal and the power-on signal transmitted from the electrical device or gas device whose power is turned on via the communication unit, In step S14, based on the received address signal, the transmission source electric device or gas device is recognized and registered under management, and the control signal indicating that the electric device or gas device has been registered under management. Is transmitted via the communication means. Thereby, it recognizes that the electric equipment and gas equipment were put under management of the earthquake detection control apparatus 11 and the fire detection control apparatus 12 in step S15.

  In response to this, the earthquake detection control device 11 and the fire detection control device 12 recognize and manage the control target device whose power is turned off among the control target devices registered under management among the registered control target devices. Performs interrupt processing to remove from the bottom. That is, in step S23, the earthquake detection control device 11 and the fire detection control device 12 receive the address signal and the power-off signal transmitted from the electric device or gas device whose power is turned off via the communication unit, In step S24, based on the received address signal, the transmission source electric device or gas device is recognized and removed from the management, and a control signal indicating that the electric device or gas device has been removed from the management is received. Transmit via communication means. Thereby, it is recognized that the electric device and the gas device are placed under the non-management of the earthquake detection control device 11 and the fire detection control device 12 in step S25.

  In the electrical equipment and gas equipment control system that performs such initial registration and registration or deregistration of the control target equipment, when an earthquake or fire actually occurs, the earthquake detection control device 11 and A disaster signal indicating the occurrence of a disaster is transmitted from the fire detection control device 12 to the control target device registered under management.

  In response thereto, as shown in FIG. 5, when the electrical device or gas device receives the disaster signal in step S31, it transmits a reception confirmation signal indicating that the disaster signal has been received in step S32, and transmits the disaster signal. To the detected earthquake detection control device 11 and / or the fire detection control device 12. In step S33, the electric device and the gas device perform a shut-off process and turn off the power.

Here, the earthquake detection control device 11 and / or the fire detection control device 12 execute a series of processes as shown in FIG. 6 in order to control such electric devices and gas devices.

  First, in the electrical equipment and gas equipment control system, when an earthquake is detected by the earthquake detection control device 11 and its seismic intensity (vibration level) is acquired in step S41, a counter (not shown) in the earthquake detection control device 11 is shown. The output count value k is set to 0. The output count value k indicates the number of times that a disaster signal has been transmitted to an electrical device or a gas device. Then, in step S42, the earthquake detection control device 11 determines whether there is an electrical device or gas device registered under management whose control condition is set to be equal to or less than the acquired seismic intensity. Here, since it is not necessary to control the earthquake detection control device 11 when it is determined that there is no electrical device or gas device having a control condition set below the acquired seismic intensity, the processing from step S41 is performed. repeat. On the other hand, if the earthquake detection control device 11 determines that there is an electrical device or gas device whose control condition is set below the acquired seismic intensity, the process proceeds to step S44, and the electrical device or gas device is transferred. Is recognized as a control target device, a disaster signal is transmitted to these electric devices and gas devices via the communication means, and the output count value k is incremented and set to 1.

  Further, in the electrical equipment and gas equipment control system, when a fire is detected by the fire detection control device 12 in step S43, the process proceeds to step S44 as it is, and the electrical equipment and gas equipment registered under the management. Is recognized as a control target device, a disaster signal is transmitted to these electric devices and gas devices via the communication means, and the output count value k is incremented and set to 1. In addition, when the fire degree is set for each device to be controlled, the fire detection control device 12 controls the control condition among the electric devices and gas devices registered under the management, similarly to the earthquake detection control device 11. However, you may perform the process which determines whether there exists what was set below the acquired fire degree.

  Subsequently, the earthquake detection control device 11 and / or the fire detection control device 12 operates a timer (not shown) in step S45 and waits for a response from the electrical device or gas device that transmitted the disaster signal. In step S46, it is determined whether or not there is a response from all the electric devices and gas devices that have transmitted the disaster signal.

  Here, when the earthquake detection control device 11 and / or the fire detection control device 12 determines that there is a response from all the electric devices and gas devices that have transmitted the disaster signal, these electric devices and gas devices. Is recognized as having been turned off by performing the series of processes shown in FIG. 5, and then the process proceeds to the next earthquake or fire detection mode in step S41 or step S43.

  On the other hand, when the earthquake detection control device 11 and / or the fire detection control device 12 determines that there is no response from all the electric devices and gas devices that have transmitted the disaster signal, in step S47, the output count value k. Is a predetermined value km (> 1). Here, since the output count value k is 1, the earthquake detection control device 11 and / or the fire detection control device 12 shifts the processing to step S48.

  In step S48, the earthquake detection control device 11 and / or the fire detection control device 12 transmits a disaster signal to the non-responding electric device or gas device via the communication means, and increments the output count value k. Set to 2. Then, in step S49, the earthquake detection control device 11 and / or the fire detection control device 12 operates a timer (not shown) and waits for a response from the electrical device or gas device that transmitted the disaster signal, In S50, it is determined whether or not there is a response from an electric device or gas device that has not responded and has transmitted a disaster signal.

  Here, when the earthquake detection control device 11 and / or the fire detection control device 12 determines that there is a response from the non-response electric device or gas device that has transmitted the disaster signal, these electric devices Then, the gas appliance recognizes that the power supply has been turned off by performing the series of processes shown in FIG. 5, and shifts to the next earthquake or fire detection mode in step S41 or step S43.

  On the other hand, if the earthquake detection control device 11 and / or the fire detection control device 12 determines that there is no response from the non-response electrical device or gas device that transmitted the disaster signal, the processing from step S47 is performed. repeat.

  And when the earthquake detection control device 11 and / or the fire detection control device 12 determines in step S47 that the output count value k is km, that is, for an electric device or gas device that is not responding, If it is determined that there is still no response even after trying to transmit the disaster signal km times, the process proceeds to step S51, indicating that it is impossible to control an unresponsive electrical device or gas device. An error display and an alarm sound are output, and the process proceeds to the next earthquake or fire detection mode in step S41 or step S43.

  As described above, the earthquake detection control device 11 and / or the fire detection control device 12 can control the electric device and the gas device by transmitting the disaster signal via wireless communication based on Bluetooth. At this time, the earthquake detection control device 11 and / or the fire detection control device 12 takes into account a communication error that may occur between the electric device and the gas device, and the electric power that has not responded due to the first transmission of the disaster signal. Reliable control can also be performed on devices and gas devices by attempting to transmit a disaster signal a plurality of times, for example, about three times.

  In addition, in the electrical equipment and gas equipment control system, in addition to the electrical equipment and gas equipment as control target equipment, as described above, the cellular phone 15 possessed by the user US, the radio 16 and the battery are owned as necessary. The emergency light 17 of the equation is also controlled.

  That is, in the electrical equipment and gas equipment control system, when an earthquake or a fire actually occurs after performing the above initial registration for the mobile phone 15 to be controlled, the radio 16 and / or the emergency light 17. From the earthquake detection control device 11 and / or the fire detection control device 12, the mobile phone 15, the radio 16 and / or the emergency light 17 are subjected to a series of processes as shown in FIG. , Send a disaster signal indicating the occurrence of a disaster.

  In response to this, as shown in FIG. 7, when the mobile phone 15 receives the disaster signal in step S61, the mobile phone 15 receives the disaster confirmation signal indicating that the disaster signal has been received in step S62. It transmits with respect to the detection control apparatus 11 and / or the fire detection control apparatus 12. FIG. In step S63, the mobile phone 15 outputs a predetermined alarm sound or displays an alarm screen.

  As shown in FIG. 8, when the radio 16 and / or emergency light 17 receives a disaster signal in step S71, the radio 16 and / or emergency light 17 transmits a reception confirmation signal indicating that the disaster signal has been received in step S72. To the detected earthquake detection control device 11 and / or the fire detection control device 12. In step S73, the radio 16 and / or the emergency light 17 turns on the power supply that has been turned off. Thereby, the radio 16 can receive and output broadcasts such as disaster information, and the emergency light 17 can be turned on to illuminate the surroundings.

As described above, in the electrical equipment and gas equipment control system, the mobile phone 15, the radio 16, and / or the emergency light 17 are controlled as necessary in addition to the electrical equipment and the gas equipment as the control target equipment. Accordingly, for example, even when a disaster occurs while the user US is sleeping, the user US is quickly woken up by an alarm sound output from the mobile phone 15, and a broadcast or emergency light 17 output from the radio 16 is obtained. By lighting up, it is possible to contribute to causing the user US to take an appropriate action without causing a panic.

  As described above, in the electrical equipment and gas equipment control system, the function of performing wireless communication based on Bluetooth is added to the single earthquake detection control apparatus 11 and the single fire detection control apparatus 12, and the television or personal By performing shut-off control of electrical equipment such as computers and gas equipment such as gas stoves, the power of various electrical equipment and gas equipment can be turned off without the user US performing an operation to turn off the power voluntarily. And can prevent the occurrence of secondary disasters appropriately.
